Off Facebook Activity

Off Facebook Activity is a tool, that let’s Facebook users see which sites they used outside of Facebook. The tool is as creepy as you would think it would be. Facebook, through it’s like buttons and other embeds, has sheer unlimited insight into personal browsing behaviour.

In an attempt by the company to create more transparency, it discloses how much curiosity in a negative sense is driving the social network in trying to understand their audience. And actually sell this gained knowledge to their customers.

The release of Off Facebook Activity a reminder we are living in an increasingly connected world that is watching us. There is entirely no point for any company to collect this type of data outsire of making us a product.

The Washington Post writes about how creepy and scary this feature is, and even more important, how to work with privacy settings. While the article deals with Facebook internal settings alone, the amout of data transferred to Facebook won’t stop. At this point, you may want to consider personal privacy tools like uMatrix (for Firefox or Chrome). Or, to leverage protection for the entire network, e.g. for your family, Pi-Hole is worth taking a look, too.

AWS CloudFront Monitoring Update

AWS CloudFront Monitoring Update: AWS released an early & small Christmas Gift to their CloudFront Customers. CloudFront now supports eight more metrics to monitor content distribution. These include:

Cache Hit Rate via HTTP POST and PUT requests, via the percentage of all cacheable requests for which CloudFront served the content from its cache, including errors not considered cacheable requests.

Origin Latency as a quota and the total time spent for requests that are served from the origin, not the CloudFront cache. Origin Latency allows to monitor the performance of your origin server.

Error Rate by status code as a percentage of requests for which the response’s HTTP status code is in the 4/5xx range, in particular 401, 403, 404, 502, 503, and 504.

Kubernetes 1.17 released today – Open Source

Kubernetes 1.17 released today
Kubernetes Logo

Today Kubernetes released it’s version 1.17. The software is one of the most popular open source projects ever. It allows managing containerised applications and micro-services. The release arrives at the end of a regular development cycle.

After the project was announced in 2014 by two Google employees, it hit a first 1.0 milestone on July 2015. The project gained massive popularity in the cloud world because it enables scalable infrastructures and service. With the Kubernetes 1.0 release, Google partnered with the Linux Foundation to form the Cloud Native Computing Foundation (CNCF) as a new home for the technology.

Since Kubernetes became publicly available, it gained popularity quickly and today is commonly used as the main way to host microservice-based implementations, mostly because Kubernetes and its associated ecosystem provide a rich choice of tools with all the capabilities that are needed to address key concerns of any modern software architectures.

With Kubernetes 1.17 released today, the package comes with more details on the release in the Release Schedule or in particular on the Changelog.

The Road to Python3

When Python3 came out in 2009, it was already heavily debated. Python3 would be incompatible with previous versions of the popular language, but fix many drawbacks. While the vision was clear and the community initially planned to move forward much quicker. The demand for having a 2.x branch was so huge, however, that the community decided to extend support for 2.7 until the end of 2019. Stack Overflow took a look on why the path took so long.
